4d994af032 kernel: remove object tracing
Remove this intrusive tracing feature in favor of the new object tracing
using the main tracing feature in zephyr. See #33603 for the new tracing
coverage for all objects.

This will allow for support in more tools and less reliance on GDB for
tracing objects.

This removes the z_ prefix those (functions, enums, etc.) that

This adds two new APIs to the coredump subsystem to perform

for information, and to perform commands such as finding
out if there is a stored coredump.

c4de586fbe debug: coredump: no need to track errors at frontend
The coredump frontend (mostly) consists of wrappers of backend
functions so there is really no need to track errors at
the frontend level. Let the backends deal with their own errors
and this simplifies the code a bit.

5408f3102d debug: x86: Add gdbstub for X86
It implements gdb remote protocol to talk with a host gdb during the
debug session. The implementation is divided in three layers:

1 - The top layer that is responsible for the gdb remote protocol.
2 - An architecture specific layer responsible to write/read registers,
    set breakpoints, handle exceptions, ...
3 - A transport layer to be used to communicate with the host

The communication with GDB in the host is synchronous and the systems
stops execution waiting for instructions and return its execution after
a "continue" or "step" command. The protocol has an exception that is
when the host sends a packet to cause an interruption, usually triggered
by a Ctrl-C. This implementation ignores this instruction though.

This initial work supports only X86 using uart as backend.

49206a86ff debug/coredump: add a primitive coredump mechanism
This adds a very primitive coredump mechanism under subsys/debug
where during fatal error, register and memory content can be
dumped to coredump backend. One such backend utilizing log
module for output is included. Once the coredump log is converted
to a binary file, it can be used with the ELF output file as
inputs to an overly simplified implementation of a GDB server.
This GDB server can be attached via the target remote command of
GDB and will be serving register and memory content. This allows
using GDB to examine stack and memory where the fatal error
occurred.

efc5fe07a2 kernel: overhaul unused stack measurement
The existing stack_analyze APIs had some problems:

1. Not properly namespaced
2. Accepted the stack object as a parameter, yet the stack object
   does not contain the necessary information to get the associated
   buffer region, the thread object is needed for this
3. Caused a crash on certain platforms that do not allow inspection
   of unused stack space for the currently running thread
4. No user mode access
5. Separately passed in thread name

We deprecate these functions and add a new API
k_thread_stack_space_get() which addresses all of these issues.

A helper API log_stack_usage() also added which resembles
STACK_ANALYZE() in functionality.

Fixes: #17852

8ccc04de6a tracing: add infrastructure for collection of tracing data
First, this commit adds user interface in tracing_format.h which
can trace both string format and data format packet.

Second, it adds method both for asynchronous and synchronous way.
For asynchronous method, tracing packet will be buffered in tracing
buffer first, tracing thread will output the stream data with the
help of tracing backend when tracing thread get scheduled.

Third, it adds UART and USB tracing backend for asynchronous
tracing method, and adds POSIX tracing backend for synchronous
tracing way.

Also it can receive command from host to dynamically enable and
disable tracing to have host capture tracing data conveniently.

This is unmaintained and currently has no known users. It was
added to support a Wind River project. If in the future we need it

The mem_safe subsystem is also removed, it is only used by the
GDB server. If its functionality is needed in the future, it
shoudl be replaced with an exception-based mechanism.

The _image_{ram, rom, text}_{start, end} linker variables have
been left in place, they will be re-purposed and expanded to
support memory protection.
